I'd say that the chances to get pipeline/quadro mod working (even hardware mode) for new locked chips (i.e. NV41, NV43 A4, NV47 etc) are close to zero.
As far as I know, the mask defining GPU units locked for enabling (pipes and professional caps unit) is defined by bonding options. You cannot change them unless you're able to unsolder GPU, add missing balls and solder it back. In the previous unlockable chips (NV40, NV43 A2) the mask didn't actually affected the chip's functionality, it was read by BIOS and copied to another (programmable) mask register. This allowed any sofware to override mask and to enable units even if they are locked with hardwired mask defined with bonding options. In new chips NV simply seem to remove this "hole", there is no longer sowtware overridable additional mask register, and the units are masked directly by hardwied mask. And the chances to change it are close to zero.
I do hope that I'm wrong and NV still left some hole, but I'm afraid that I'm not. They were too hurted with NV40 modding and definitively tried to make future mods impossible. At least if I were NV, I'd use the strategy I described above. And they are not stupid too
